In The Walking Dead’s next episode ‘When the Dead Come Knocking’ the Governor sends Merle to push Glen and Maggie for information about Rick’s group. Meanwhile, at the prison, Rick’s hand is forced by the arrival of a new guest in the form of Michonne.

Check out the latest promo trailer from the episode below, along with two new sneak peeks. Watch as Michonne (Dannai Gurira) attempts to blend in with the Walkers at the prison – but when her wound attracts their attention, Rick must decide what to do.
